Differences between structure and class
•
2 likes•1,622 views
Structures are typically used for smaller amounts of data and cannot be inherited, abstract, or null. Classes support larger amounts of data and can be inherited, abstract, null, and have destructors. Structures are value types while classes are reference types, and only classes support events that are automatically thread-safe. Fields within structures are not automatically initialized while classes initialize fields to default values.

struct and class deferences
Structures are collections of variables of different data types, while classes can also contain functions. The main differences are: structures have public access by default, are used for small data groups, and objects are stored on the stack. Classes have private access by default, are used for larger amounts of data with abstraction and inheritance, and objects are stored on the heap. Both allow variables, functions, constructors/destructors, and inheritance, but classes provide more robust features for object-oriented programming.
Structure prespentation
Structures allow the grouping of different data types under a single name for easier handling. A structure is declared using the struct keyword followed by the structure name and members inside curly braces. Structure members can be of similar or different data types. Structure variables are then declared using the structure name. This allows storing multiple related data under one variable name. Arrays differ in that they contain elements of the same data type, while structures can mix data types.
Structure
Structures allow users to define their own data types that group together variables of different types under a single name. A structure is defined using the struct keyword followed by member variables enclosed in braces. Structure variables can then be declared and accessed using the member operator (.). Structures can contain other structures (nested structures), and pointers to structures allow structures to be passed to functions and dynamically allocated. Linked lists are a common data structure that use structures - each list node contains a struct with a data element and pointer to the next node, with the list connected via these pointers.
C programing -Structure
The document discusses structures in C programming. It defines a structure as a user-defined data type that allows combining different data types under a single name. Structures are used to represent records with multiple attributes. The document explains how to declare and define structures with tags, and access structure members using dot and pointer operators. It provides an example of a nested structure and a program demonstrating the use of functions and pointers with structures.
C Structures & Unions
C structures allow grouping of related data items under one name. Structures are scalars that can be passed as function arguments or assigned to variables. Unions share the same memory region for all members, so only one member can be accessed at a time. Both structures and unions allow organizing related data and passing groups of data together.
#Jai c presentation
Structures allow users to define custom data types that group together variables of different types under a common name. Structures can contain arrays of other structures to create complex data structures. Nested structures contain structures within other structures, and can be defined separately or embedded within the containing structure. Pointers to structures allow structures to be passed to functions and their members accessed using the arrow operator.

The document discusses C structures and provides examples. Some key points:
- Structures allow grouping of different data types under a single name. This is useful for representing records like books with attributes like title, author, etc.
- To define a structure, the struct statement is used along with member definitions of different data types. Structure variables can then be declared.
- Structures can be accessed using dot (.) or arrow (->) operators with structure variables or pointers. Arrays of structures allow storing multiple records.
- Structures can be passed to functions by value or by reference. Global structure variables are visible to all functions without needing to pass.
- Structure memory allocation packs elements contiguously
populators&Converters
This document discusses populators and converters in Hybris. It defines populators as copying data from a source business object to a facade data object (POJO), while converters create new data objects and call populators to populate them. It recommends using Spring configuration to call populators from converters rather than directly in code. The approach is to encapsulate conversions in populators and make data private with getters/setters. An example flow shows how a populator populates a description field to be viewed in the frontend. Configurable populators can invoke specific populators based on data options for performance.

Structures allow grouping of heterogeneous data types into a single unit called a structure. Structures can contain integer, float, double, character data and arrays. Structures are accessed using the dot operator. Unions share the same memory location for different data types and can hold data of only one member at a time. Enumerated data types define user-defined data types using the enum keyword where symbolic constants take on integer values starting from zero.
Diversity Filtering
The document discusses diversity filtering of molecule datasets. It introduces dividing a dataset into diverse and similar molecules based on a similarity threshold.

The methodology calculates similarity matrices and scores, while the implementation includes functions for fingerprint similarity, diversity scoring, and filtering molecules by threshold into diverse and similar sets.
Lecture19 unionsin c.ppt
A union allows a chunk of memory to store different data types but only one at a time. It allocates enough space for the largest data type defined. Assigning a value to one member overwrites the previous content. Unions save memory when only one type is needed at a time compared to structures that allocate space for all members. The syntax defines a union type name containing different variable types, then a variable of the union type can access members to store a value.
Constant a,variables and data types
This document discusses constants, variables, and data types in Java. It defines two main data types - primitive and reference/object. The eight primitive data types are char, int, byte, float, long, short, double, and boolean. Reference variables are created using class constructors. There are three types of variables - local, instance, and class/static. Local variables are declared in methods/constructors/blocks and are only visible there. Instance variables are declared in a class but outside methods/constructors/blocks. Class variables are declared with the static keyword and can be accessed via the class name. Constants are declared with the final keyword and hold the same value during their existence.
Introduction linked list
This document provides an introduction to linked lists. It discusses structures and pointers in C, as well as static and dynamic memory allocation. Linked lists are introduced as a data structure that uses dynamic memory allocation. A linked list is made up of nodes, with each node containing data and a pointer to the next node. This allows linked lists to grow and shrink dynamically at runtime, unlike arrays which have a fixed size. Common linked list operations like traversal, insertion, deletion and searching are also mentioned.

2013 11 CSharp Tutorial Struct and Class
Structs are value types that allocate memory on the stack, while classes are reference types that allocate objects on the heap. The 'new' operator is used to instantiate structs and classes, which for structs always initializes fields, while for classes uses parameterless constructors if defined or adds a default one. Equality for structs uses both '==' and 'Equals()' by comparing fields, while for classes '==' compares references and 'Equals()' is implemented by the class.
Week3 dq1
A class contains two basic elements - state and behavior. The class must include a constructor to define these elements. A class definition specifies class statements and object constructors. A class can inherit properties from a superclass defined in its constructor. The code sample shows a class declaration that subclasses MySuperClass and implements MyInterface. It defines public and private state variables and a constructor that initializes them. Getter and setter methods allow modifying and accessing the class state through its objects.

Union In language C
The document discusses unions in C programming. A union is like a structure that allocates space for its members equal to the largest member. Only one member can be accessed at a time. The document provides an example union for employee data and explains memory allocation. Unions allow different variable types to share the same memory space. Structures are used for database management and other applications while unions are useful when variables need to share the same memory location.

This document discusses dynamic memory allocation and linked lists. It describes functions like malloc, calloc, free, and realloc for allocating and releasing memory at runtime. It also explains the concepts of linked lists, where each node contains data and a pointer to the next node, allowing flexible growth and rearrangement but slower random access than arrays.#OOP_D_ITS - 4th - C++ Oop And Class Structure
1. C++ classes represent groups of similar instances, with fields that define each instance and methods that operate on instances.
2. The document discusses class access modifiers like public and private, and how they control access to class fields and methods. It also covers class methods like accessors, mutators, and static fields.
3. Class constructors and destructors allow initialization and cleanup of class instances, running automatically when instances are created and destroyed.
Constructor & destructor
- Constructors are special member functions used to initialize objects when they are created. They are automatically called upon object creation and have the same name as the class. Constructors can be default, parameterized, or copy constructors.
- Destructors are also special member functions that perform cleanup actions when an object is destroyed, such as freeing memory. They are called automatically upon object destruction and have the same name as the class preceded by a tilde.
- Examples demonstrate default, parameterized, and copy constructors as well as destructors being defined and called for a class to properly initialize and cleanup objects.

C++ Inheritance
Inheritance allows one class to inherit attributes and behaviors from another existing class. This helps with code reuse by extending an existing class without modifying it. A derived class inherits from a base class, and any changes to the base class will also affect the derived classes. Abstract classes define common behaviors for other classes to inherit from but cannot be instantiated themselves, instead forcing subclasses to implement abstract methods.

Object Oriented Programming with C#
The document provides an overview of object-oriented programming concepts in .NET such as classes, objects, methods, constructors, destructors, inheritance, polymorphism, interfaces, access modifiers, and static members. It defines each concept and provides examples to illustrate how they are implemented in C#.
OOPs difference faqs- 2
The document compares several concepts in programming:
1. Events can be used in interfaces but delegates cannot. Events have add/remove accessors while delegates do not. Events have a specific signature while delegates do not.
2. A class is a template for objects while an object is a real implementation in memory. Classes define logic for reuse while each object has its own data.
3. A private constructor is called after object creation while a static constructor initializes static members before any objects are created. Private constructors initialize each object while static constructors run only once.
4. Properties represent data via getters/setters while methods perform actions via defined signatures.
5. The singleton pattern ensures
Inheritance in java.ppt
Inheritance allows classes to extend existing classes, reusing and building upon their attributes and behaviors. This supports polymorphism by allowing parent and child classes to be treated the same when interacting with their common attributes and methods. Well-known inheritance hierarchies include shapes (like rectangles and circles) inheriting from a parent shape class, or employees inheriting from a main employee class. Inheritance promotes code reuse and flexibility.

Classes and interfaces lie at the heart of the Java programming language. They are its basic units of abstraction.
This chapter contains guidelines to help you make the best use of these elements so that your classes and interfaces are usable, robust, and flexible.
C# question answers
The document contains questions and answers about various C# concepts. Key points covered include:
- C# supports single inheritance through the colon syntax but not multiple inheritance. Interfaces can be used instead.
- Private class variables are inherited but not accessible in derived classes. Protected internal variables are accessible to derived classes in the same assembly.
- When overriding a method, the signature must remain the same but the virtual keyword changes to override. Private and static methods cannot be overridden.
- Abstract classes cannot be instantiated and derived classes must implement abstract methods. Interfaces contain only public abstract methods that must be implemented.
- String is immutable while StringBuilder allows mutable string operations. Namespaces group related

Micro Anti-patterns in Java Code
This document describes several micro-level antipatterns in Java code, including:
1) Constant interface - An interface with only static final fields and no methods. This violates encapsulation principles.
2) Concrete root - When the base class of an inheritance hierarchy is concrete rather than abstract. Experienced designers usually make the root abstract.
3) Circular dependency - When two or more classes depend on each other, making it difficult to construct objects and causing other issues.
The document provides examples and explanations for each antipattern to help developers avoid these pitfalls in their code design. It draws from several references on software design best practices.
Java Core Parctical
A constructor is used to create objects and has the same name as the class with no return type. A method is an ordinary member function that can have its own name and return type.
The purpose of garbage collection is to identify and discard objects no longer needed by a program to reclaim memory. An object becomes eligible for garbage collection when it is unreachable.
Synchronization controls access to shared resources for multithreading by preventing one thread from modifying a variable while another thread is using it, which can cause errors.
An abstract class cannot be instantiated and is meant to serve as a template for subclasses to extend, while an interface can only declare constants and abstract methods but provides no implementation.
C# program structure
This document provides an overview of C# program structure and key concepts like namespaces, classes, structs, interfaces, enumerations, delegates, and abstract classes. It defines each concept, provides examples, and explains when to use each one and how they relate to each other. Namespaces help organize code, classes and structs define custom types, interfaces define common functionality, enumerations define named constants, delegates define callbacks, and abstract classes define common traits.
Object Oriented Best Practices - Summary
Here is a summary of object oriented best practices covered in my book "60 Tips on Object Oriented Programming" (Tata McGraw Hill, 2007).
PACKAGES, MULTITHREADED PROGRAMMING & MANAGING ERRORS AND EXCEPTIONS in java
1) Packages in Java are used to organize classes and interfaces into logical groups. They provide access protection and prevent naming collisions. There are built-in packages provided by Java as well as user-defined packages that can be created.
2) Multithreading allows multiple tasks to be performed simultaneously by executing threads in parallel. Threads are lightweight subprocesses that can execute concurrently, improving performance. The main threading constructs in Java are the Thread class and Runnable interface.
3) Synchronization in Java controls access to shared resources by multiple threads. The synchronized keyword is used to prevent interference and consistency issues when threads access the same code or data concurrently.
Design patterns difference between interview questions
The document summarizes differences between various design patterns and programming concepts. It compares Factory Pattern vs Abstract Factory Pattern, Builder Pattern vs Abstract Factory Pattern vs Composite Pattern, MVC vs MVP, Proxy Pattern vs Observer Pattern, Strategy Pattern vs Inversion of Control, IDictionary vs Dictionary, Factory Pattern vs Dependency Injection, String.Clone() vs String.Copy(), Strategy Pattern vs Factory Pattern, Proxy vs Adapter, Decorator vs Visitor patterns.
Java basics
The document discusses key concepts in Object Oriented Programming (OOP) in Java including classes, objects, references, constructors, inheritance, abstraction, polymorphism, and generics. It defines classes as blueprints for objects, and objects as instances of classes that have state and behavior. Constructors are used to initialize new objects. Inheritance and abstraction allow classes to extend and implement other classes and interfaces. Polymorphism enables different classes to implement the same methods in different ways. Generics provide type safety for collections of objects.
Encapsulation
Encapsulation is one of the four fundamental object-oriented programming concepts along with inheritance, polymorphism, and abstraction. It involves wrapping code and data together into a single unit. Encapsulation hides internal implementation details of a class and protects it from accidental changes, while allowing the class to control how its data is accessed and stored.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Differences between structure and class
- 1. Differences B/W structure ans class. 1. Classes are usually used for large amounts of data, whereas structs are usually used for smaller amounts of data. 2. Classes can be inherited whereas structures not. 3. A structure couldn't be null like a class. 4. A structure couldn't have a destructor such as a class. 5. A structure can't be abstract, a class can. 6. Structures are value types and the classes are reference types. 7. Declared events within a class are automatically locked and then they are thread safe, in contrast to the structure type where events can't be locked. 8. A structure must always have the default parameter less constructor defined as public but a class might have one, so you can't define a private parameter-less constructor as in the following: struct Me { private Me()// compile-time error { } } class Me { private Me()// runs Ok{ } 9. The strucutre can't conatain a volatile field whereas the class can 10. You can't use sizeof with classes but you can with structures 11. Fields are automatically initialized with classes to 0/false/null wheatheras strucutres are not 12. Fields can't be directley instantiated within structures but classes allow such operations as in the following:
